Résumé : Axial and non-axial octupole excitations built on superdeformed states of zero spin in 192,194Hg and 194Pb nuclei are studied within the fully microscopic generator-coordinate method using selfconsistent Hartree-Fock BCS states as a basis. Results with the effective interaction SkM* predict vibration energies of 1.9-2.5 MeV, B(E3) values of 15-37 single-particle units and unusually large B(E1) transition rates up to 0.02 W.u. Calculations including both octupole modes with K = 0 and K = 2 indicate that these modes couple weakly.
